convert SF7 to GEMC map

For solenoid type of magnet, assume azimuthal symmetry.

SF7 map format produced by Possion program SF7.exe contain text lines for explanation, map range and grid size, map values (R, Z, Br, Bz, B, A, dBz/dr, dBr/dz, field index).

GEMC map format requires R, Z, Br, Bz

Additional difference is SF7 map values are in order of R increasing first when Z is fixed, while GEMC map values are in order of Z increasing first when R is fixed.

Thus the conversion program at svn "
